Don't. Let the dealer do it as part of the sale (you usually get free installation on accessories you buy at the time of purchase).
My brother and I spent an hour struggling to get one of the front mud flaps on last night and failed. Damn brackets kept popping off (now the clips are stuck in them so we probably have to buy new brackets) and couldn't get the "self-tapping" screws into the plastic. It's almost impossible w/o taking the wheels off despite what the instructions say. I think you'd need a power screwdriver to get enough speed on the screws to tap into the plastic liner.
They should make their engineers put on the stuff they design so they see how much their hands hurt afterwards. And do oil changes. And anything else a DIYer might try. Ack.
